Based on similar question:

I want it to also remove trailing spaces on a line. The accepted answer might have this initialization instead:

        Dim originalText As String = vbCrLf & "Second line." & vbCrLf & _
            "  Third line, with leading space and trailing spaces.      " & vbCrLf & _
            vbCrLf & "Fifth line." & vbCrLf

How would it be, now?

Hi GivenRandy;

Try it this way. It will remove all white space before and at the end of each line.

        Dim originalText As String = vbCrLf & "Second line." & vbCrLf & _
            "  Third line, with leading space." & vbCrLf & _
            vbCrLf & "Fifth line." & vbCrLf
        Dim cleanedText As String = Regex.Replace(originalText, _
            "^(?<1>\r\n)*(?<2>\s*)(?<3>.*?)\s*$", _
            "$3" & vbCrLf, RegexOptions.Multiline)
        MessageBox.Show("-->" & cleanedText & "<--")

Hi GivenRandy;

Sorry about that but I overlooked the replacement string when I adjusted the Regex pattern string. So replace this

    "$3" & vbCrLf

With this

    "$3"

Or copy and past this line into the code replacing the last one I posted.

        Dim cleanedText As String = Regex.Replace(originalText, _
            "^(?<1>\r\n)*(?<2>\s*)(?<3>.*?)\s*$", _
            "$3", RegexOptions.Multiline)

Works precisely. Thanks!

By the way, I picked up the book "Master Regular Expressions" so that maybe I can improve my RegEx skills more quickly. Thanks for your help!

I'm gonna have one more, with all of them laid out. I'm getting the hang of it, but still not getting all of them at once.

You have been doing them correctly, but I keep adding specs (spec creep).
